N951CC more squawks found and resolved

While I was out flying a few weeks ago, I decided to fly the ILS approach at Palmdale because I hadn't had a chance to verify the ILS after maintenance. Good thing too because I found that the marker beacon and glideslope was inop. It turns out that the marker was decommissioned (after I flew the approach) and locals were saying it has been down for a while, so that test was invalid.

After thinking about the glideslope, another local noticed that the needle didn't twitch like the CDIs when the avionics master was turned on or off. This made me think that it wasn't connected, or at least not getting a signal. I didn't swap the cables to the indicators because they were responding properly to the frequencies in the radios. Turns out that the KX-155A can be configured with or without a glideslope receiver.

It is easy to see how two CDIs are beneficial, but you can't fly two different glideslopes at the same time, so there is no benefit to two glideslope receiver equipped KX-155As. It turns out that when I swapped the radios trying to track down the comm 2 issue, I moved the radio with the glideslope to comm two. Once I swapped them back, I could now see the glideslope twitch with the avionics master. On our last flight, I flew a practice ILS into Ontario and confirmed the proper operation of the marker beacon and the glideslope.

In other news, the fuel transducer is at EI right now and I should have a replacement to install.
